Patent CA-2270453-A1 (CA)
Title: Level measuring device operating with microwave
Inventor: MUELLER ROLAND
IPC: G01S13/10
Filed: 1999-04-30
Abstract: A level measuring device suitable for highly accurate measurements. A transmission pulse generator generates microwave pulses at a transmission repetition rate and transmits them through an antenna towards a material whose level is to be measured. Echo signal from the surface of the material are received by the antenna. A reference pulse generator generates reference pulses similar to the transmission pulses but at a reference repetition rate which differs form the transmission repetition rate by a small frequency difference. The echo signal and reference pulse are input to a first mixer which generates an intermediate frequency signal that, with respect to the echo signal, is slowed by a time dilation factor equal to the quotient of the transmission repetition rate and the frequency difference. A first subcircuit samples the intermediate frequency signal, the time interval between two successive samplings equaling a time unit. A differential signal generator generates a differential signal which changes with the frequency difference. A second subcircuit determines the period of the differential signal on the basis of the time unit. An evaluation unit determines an actual time interval between two points of the echo signal corresponding to the two sampling points.

Title: Multiple column nitrogen generators with oxygen coproduction
Inventor: HOPKINS JEFFREY ALAN
IPC: F25J3/04
Filed: 1999-05-26
Abstract: The present invention is an improvement to a nitrogen generator enabling the process to efficiently coproduce oxygen with low recovery, typically less than 70% and preferably less than 55%, in addition to the primary product, nitrogen. In the nitrogen generator process, air is distilled in a distillation column system having a higher pressure column and a lower pressure column. The feed air is compressed, treated to remove water and carbon dioxide, cooled to near its dew point and red to the higher pressure column of the distillation column system. The nitrogen product is produced by removing an overhead vapor stream from at least one of the columns of the distillation column system. At least one oxygen-enriched stream is removed from the lower pressure column. The improvement is characterized in that: (a) the oxygen-enriched stream is removed from the lower pressure column at a location that is at or below the feed to the lower pressure column; (b) feeding the removed oxygen-enriched stream to a supplemental distillation column for separation into an oxygen bottoms and a waste overhead; (c) providing boilup to the supplemental distillation column and (d) removing an oxygen stream (vapor or liquid) from the bottom of the supplemental distillation column as an oxygen product.

Title: Biological tissue stimulation by optical energy
Inventor: BELLINGER GARY J
IPC: A61N/
Filed: 1998-01-09
Abstract: Biological tissue of a living subject is irradiated with optical energy at a wavelength and at a power dissipation level to cause the amount of optical energy absorbed and converted to heat in the tissue to be within a range bounded by a minimum absorption rate sufficient to elevate the average temperature of the irradiated tissue to a level above the basal body temperature, but which is less than the absorption rate at which tissue is converted into a collagenous substance. According to this method, a therapeutic, warming effect is produced within the irradiated tissue, but without causing tissue damage by thermal overheating. The method of using a low level reactive laser system from 100 milliwatts per square centimeter to 1000 milliwatts per square centimeter in either a pulsed or continuous mode with optical energy produced by a Nd:YAG laser at a fundamental wavelength of 1,064 nanometers has been found to reduce pain in soft tissues, reduce inflammation and enhance the healing of tissue by stimulation of microcirculation without subjecting the living tissue to damaging thermal effects. The energy density of the irradiated tissue is limited to the range of from about .1 joule per square centimeter to about 15 joules per square centimeter. An alternative method produces optical energy by an Nd:YLF laser at a wavelength of 1,055 nanometers. Other lasers could be used which would produce optical energy in a preferred range of from about 950 to about 1,200 nanometers at the desired power range.
